Valery Shatrov returns to a service after being seriously wounded. He manages to become “his own” in the complicated team of the Criminal Investigation Department of Leutenant Colonel Roubtsov. The thief in law whose name is Greek treats Shatrov with respect and is not against to help him with some information unless this contradicts his own interests. But Shatrov’s life does not become easier. There is a new member in the team – Igor Bodrich, experienced investigation officer transferred from Moscow. Intelligent and experienced professional, Bodrich arises suspicions among his new colleagues on having connections with crime – he doesn’t have established authorities and he easily squanders big money. The ambulance doctor Irina finally breaks up with Shatrov and leaves the city. Larisa, a businesswoman, who is Shatrov’s neighbour starts flirting with him, at the same time he gets acquainted with a psychotherapist Sofia and begins to attend her sessions. Clarity and simplicity in Shatrov’s personal life is not expected.
An unexpected ally of investigation officers is the new chairman of the city court Muzichenko, who also tries to set his own order in the city and puts an ultimatum to the Greek and his men – they must get out of the city.

With each new crime Shatrov and his colleagues realize that many of seemingly not connected events are links of the same chain. They have to find out who is this mysterious puppeteer and return law and order to the streets of their city.
